Amathinidae, is a taxonomic family of mostly small and minute sea snails, marine heterobranch gastropod molluscs or micromolluscs. Molluscs are animals belonging to the phylum Mollusca. There are around 250000 extant Species within the phylum with an estimated 70000 The class Gastropoda or the gastropods, also previously known as gasteropods, or univalves, and more commonly known as Snails Orthogastropoda is one of two major Taxonomic groupings of snails and slugs an extremely large Subclass within the huge class Gastropoda. Heterobranchia, the heterobranchs, (meaning "different-gilled snails" is a Taxonomic Superorder of sea Snails marine Above the species level close to 400 named taxa are referred to the gastropod superfamily Pyramidelloidea. Taxonomy is the practice and science of classification The word comes from the Greek, taxis (meaning 'order' 'arrangement' and, nomos In Biological classification, family ( Latin The word snail is a Common name that can be used for almost all members of the Molluscan class Gastropoda which have coiled shells in the Marine is an Umbrella term. As an adjective it is usually applicable to things relating to the Sea or Ocean, such as Marine biology, Marine Heterobranchia, the heterobranchs, (meaning "different-gilled snails" is a Taxonomic Superorder of sea Snails marine The class Gastropoda or the gastropods, also previously known as gasteropods, or univalves, and more commonly known as Snails Molluscs are animals belonging to the phylum Mollusca. There are around 250000 extant Species within the phylum with an estimated 70000 A micromollusk is a descriptive term for a shelled Mollusk which is extremely small even at full adult size It presently comprises less than 100 recent and fossil species divided into seven genera: Amathina, Amathinoides, Carinorbis, Cyclothyca, Iselica, Leucotina, and, Phasianema. FOSSIL is a standard protocol for allowing serial communication for Telecommunications programs under the DOS Operating system. Two additional genera, Faluniella and Plicifer may also be a part of Amathinidae. Together with Pyramidellidae, Ebalidae, Turbonillidae, Odostomidae and otherb genera they are forming the superfamily Pyramidelloidea. Pyramidellidae, Common name the pyram family, or pyramid shells, is a voluminous Taxonomic family of mostly small and minute Ebalidae is a family of minute sea Snails marine Gastropod Molluscs in the superfamily Pyramidelloidea - the pyrams Above the species level close to 400 named taxa are referred to the gastropod superfamily Pyramidelloidea. Little is known on the biology of the group, but some data on the anatomy and systematic position is given by Ponder (1987) and Huber (1993).

Anatomy
The shells are usually flat without coiling. They usually have strong axial ribs. Ponder described gigant neurons in the cerebral ganglion.
